Assuming the null hypothesis is Ho: pi1-pi2=0, compute the value of the test statistic z where 422 in a sample of 2,620 from the first population exhibited the characteristic of interest and 484 in a sample of 3,201 from the second population exhibited the characteristic of interest.
Please input into excel therefore that I can see it working and giving the correct answer. Answer the following
Let are the population proportions.
1. Null Hypothesis H0
2. Alternative Hypothesis H1
5. Value of the test statistic.
Value of the test statistic z= 2.41
